System Installation Check
• After the Aeris system is completely installed, but before the trailer is put back into service, all air
system connections need to be checked for leaks. Apply a soapy/water solution to all air
connections. If bubbles appear at any fitting or air connection, check connection to verify it is tight.
Follow Instructions Below:
 Make sure the petcock valve on the trailer air tank is closed.
 Fill the trailer air system and set all tire pressures just below the target pressures.
 Ensure the mini ball valve on the controller box is in the open position.
 Verify the trailer is connected to 12-volt power source.
 Verify the “Red” light on the circuit board in the control box is blinking. If after applying 12-
volts you don’t see the light blinking, disconnect the 12-volt power source and check all wire
terminal connections and connections to the 7 pin connector box correct.
 Indicator light on trailer should come on and blink 3 times. If insufficient pressure exists in the
system, the light will blink in a pattern of 1-long and then 2 short blinks, if low flow exists the
light will stay on constantly and if high flow exists the light will blink constantly.
 If the indicator light remains on and the system continues attempting to inflate one or more
tires to the proper pressure but can’t due to the inability to maintain adequate pressure, the
system has a leak and must be repaired.
 Verify the oil level in each wheel end is at the correct level.
